hi im new here so i dont no if this post is right i tried to to use the ws2811 a 50 led string i connected it to my uno and installed a program to use vixen 3 it uses the fastled now when i open up vixen the leds start to chase just one at a time from end to end the vixen has no program set up yet so i set up vixen as instructed and did a basic bars now this runs ok but the single chaser is still running and i cant stop it. i also tried on a mega and another uno it still does this can anyone help please thankyou


#include "FastLED.h"

#define NUM_LEDS 22
#define DATA_PIN 3

#define CLOCK_PIN 13

CRGB leds[NUM_LEDS];

// BE CAREFUL w/DEBUG!
// If you turn this on, do NOT expect a high refresh rate
// w/out some bytes getting missed. The Serial library takes
// a certain amount of time to output data, if too much data
// is output too quickly, it may not allow time to read before
// the UART buffer fills up. This can
// be improved by commenting out DEBUG sections you don't need
//boolean DEBUG = false;

void setup() {

// Uncomment/edit one of the following lines for your leds arrangement.

Serial.begin(9600);

}


void loop() {


for(int i = 0; i < NUM_LEDS; i++) {
if (Serial.available() > 0) {
Serial.readBytes( (char*)leds, NUM_LEDS * 3);

}
FastLED.show();
}

}

nothing happens till i open vixen then it chases and i haven't started to program vixen
i have tried other fastled sketches but none of them work this is the only one i can get to do anything
thanks for any help
